Perinatal mood and anxiety disorders (PMADs) affect approximately 1 in 5 birthing parents and 1 in 10 non-birthing partners (Wisner et al., 2013). They are the most common complication of pregnancy and the postpartum period, yet remain underscreened and undertreated. This screening covers the three most common postpartum presentations: depression, anxiety, and intrusive thoughts. It is adapted from validated instruments including the Edinburgh Postnatal Depression Scale (Cox et al., 1987) and the Postpartum Specific Anxiety Scale (Fallon et al., 2016). It is a screen, not a diagnosis; an elevated score warrants follow-up with a perinatal mental health clinician. Score: rate each item 0 (not at all), 1 (sometimes), 2 (often), or 3 (most of the time). Sum each section.
